Abstract

The invention relates to a process system and a process method, aiming at the preparation of vitamin C ascorbyl glucoside. The process system comprises a plurality of groups of ion exchange columns and a membrane filter, wherein the ion exchange columns are mutually connected end to end via circulation pipes and achieve a circular dynamic process including the steps of adsorption, elution and ion resin regeneration; the emission of effluent is reduced; the process cost is lowered; a chemical industry separation extraction process is applicative.

Description

technical field [0001] The invention relates to chemical equipment and a chemical process method. Background technique [0002] Vitamin C glucoside (ascorbyl glucoside), 2-O-a-D-glucopyranosyl ascorbic acid (AA-2G), is a derivative of VC, and AA-2G is one of the six whitening additives approved by the Department of Health. It can directly discharge the melanin that has formed in the epidermis (that is, accelerate the reverse reduction of the formed melanin to its original form), and its whitening effect is more obvious and faster than other additives, so it is widely used in a variety of high-end whitening cosmetics. In the process of preparing AA-2G, the separation and purification process is more difficult. The prior art adopts ion resin static adsorption and elution, discharges a lot of waste liquid, and consumes a lot of materials for resin regeneration. Contents of the invention [0003] Purpose of the invention: In order to overcome the above-mentioned defects, the...
